The system is automatically interrupted in the
following situations:▷When the brakes are applied.▷When selector lever position D is disen‐
gaged.▷When DTC Dynamic Traction Control is
activated or DSC is deactivated.▷When DSC is actively controlling stability.▷When SPORT+ is activated with Driving
Dynamics Control.▷If the safety belt and the driver's door are
opened while the vehicle is standing still.▷If the system has not detected objects for
an extended period, e.g., on a road with
very little traffic without curb or shoulder
markings.▷If the detection range of the radar is dis‐
rupted, e.g., by dirt or heavy fog.▷After a longer stationary period when the
vehicle has been braked to a stop by the
system.
Maintaining, storing, and changing the
speed
Information WARNING
The desired speed can be incorrectly ad‐
justed or called up by mistake. There is risk of
an accident. Adjust the desired speed to the
traffic conditions. Watch traffic closely and ac‐
tively interfere in the respective situations.◀
WARNING
Risk of accident due to too high speed
differences to other vehicles, e.g. in the follow‐
ing situations:
▷When fast approaching a slowly moving
vehicle.▷Suddenly swerving vehicle onto the own
lane.▷When fast approaching standing vehicles.
There is risk of injuries or danger to life. Watch
traffic closely and actively interfere in the re‐
spective situations.◀
Maintaining/storing the speed Press button.
Or:
Press the rocker switch while the system is in‐
terrupted.
When the system is switched on, the current
speed is maintained and stored as the desired
speed.
This is displayed in the speedometer and
briefly in the instrument cluster, refer to
page 148.
DSC Dynamic Stability Control will be
switched on if needed.
Changing the speed
Press the rocker switch up or down repeatedly
until the desired speed is set.
If active, the displayed speed is stored and the
vehicle reaches the stored speed when the
road is clear.
▷Each time the rocker switch is pressed to
the point of resistance, the desired speed
increases or decreases by approx.
1 mph/1 km/h.Seite 147Driving comfortControls147
Online Edition for Part no. 01 40 2 963 410 - VI/15
▷Each time the rocker switch is pressed
past the point of resistance, the desired
speed increases or decreases by a maxi‐
mum of 5 mph/10 km/h.
Hold the rocker switch in position to repeat the
action.
Distance WARNING
The system does not relieve from the
personal responsibility. Due to the system lim‐
its, braking can be late. There is risk of acci‐
dents or risk of property damage. Be aware to
the traffic situation at all times. Adjust the dis‐
tance to the traffic and weather conditions and
maintain the prescribed safety distance, possi‐
bly by braking.◀
Reduce distance Press button repeatedly until the de‐
sired distance is set.
Instrument cluster will display selected dis‐
tance, refer to page 149.
Increase distance Press button repeatedly until the de‐
sired distance is set.
Instrument cluster will display selected dis‐
tance, refer to page 149.
Calling up the desired speed and distance
While driving Press button with the system
switched on.
In the following cases, the stored speed value
is deleted and cannot be called up again:
▷When the system is switched off.▷When the ignition is switched off.While standing
The system brought the vehicle to a complete
standstill:▷Green marking in the speedometer:
Your vehicle accelerates automatically as
soon as the vehicle in the range of the ra‐
dar sensor moves off.▷Speedometer markings turn orange: no au‐
tomatic driving off.
To accelerate to the desired speed auto‐
matically, press the accelerator or press
the RES or SET button.
Rolling bars in the distance display indicate
that the vehicle detected by the radar sensor
has driven off.
The system was paused or your vehicle was
brought to a halt actively through stepping on
the brake pedal and it is standing behind an‐
other vehicle:
1. Press button to call up a stored
desired speed.2.Release the brake pedal.3.Step on the accelerator briefly, or press the
RES rocker switch when the vehicle ahead
of you drives away.

Cornering
If the desired speed is too high for a curve, the
speed is reduced slightly, although curves can‐
not be anticipated in advance. Therefore, drive
into a curve at an appropriate speed.
In tight curves the system offers only restricted
detection where a vehicle ahead of you might
be detected late or not at all.
When you approach a curve the system may
briefly report vehicles in the next lane due to
the bend of the curve. If the system deceler‐
ates you may compensate it by briefly acceler‐
ating.
After releasing the gas pedal the system is re‐
activated and controls speed independently.
Driving away In some situations, the vehicle cannot drive off
automatically; for example:
▷On steep inclines.▷From behind bumps in the road.
In these cases, step on the accelerator pedal.
Weather
In the event of unfavorable weather and light conditions, e. g. if there is rain, snowfall, slush,
fog or glare, this may result in poorer recogni‐
tion of vehicles as well as short-term interrup‐
tions for vehicles that are already detected. Drive attentively, and react to the current trafficsituation. If necessary, intervene actively, e.g.
by braking, steering or evading.
Malfunction
The system cannot be activated if the radar sensor is not aligned correctly. This may be
caused by damage incurred during parking,
e.g.
A Check Control message is displayed if the
system fails.
The function for detecting and responding
when approaching stationary vehicles may be limited in the following situations:▷During calibration of the camera immedi‐
ately after vehicle delivery.▷If the camera is malfunctioning or dirty. A
Check Control message is displayed.
Cruise control
The concept The system maintains a preset speed via the
buttons on the steering wheel. The system
brakes on downhill gradients if engine braking
is insufficient.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.
